SYNTHETIC PROSPECTING MODEL DEVELOPED FROM XIAOREQUANZI COPPER DEPOSIT IN EAST TIANSHN,XINJIANG

The Xiaorequanzi copper (zinc) deposit is situated in the south of a paleovolcanic domain in the Haerlik-Danahu late Palaeozoic continental margin island. The ore-bearing rocks are volcanic pyroclastics of Lower Carboniferous Xiaorequanzi Formation. The formation of high-grade ore body has undergone a complex process. The deposit is of marine volcanic ash-flow sedimentary -hydrothermal transformed type. Geological and physical geography as well as geochemical features are clear as effective symbols for prospecting. A synthetic prospecting model is set up through these features, which is significant for future prospecting of similar copper deposits in East Tianshan and Xinjiang.
